WARM3CH writes "AnandTech tested a laptop with an AMD CPU, a laptop with an Intel CPU, and a netbook to compare battery life while running Internet Explorer 8, Opera 10, Firefox 3.5, Safari 4, and Chrome. They tested on simple web pages and flash-infested ones. IE8 had the best battery life on both laptops (followed by FF + AdBlock), and Safari had the worst battery life. On the netbook, Chrome was slightly ahead of IE8. The report concludes: 'Overall, Internet Explorer and Firefox + AdBlock consistently place near the top, with Chrome following closely behind. Opera 10 Beta 3 didn't do as well as Opera 9.6.4, and in a couple quick tests, it doesn't appear that the final release of Opera 10 changes the situation at all. Opera in general — version 9 or 10 — looks like it doesn't do as well as the other major browsers. Safari is at the back, by a large margin, on all three test notebooks. We suspect that Safari 4 does better under OS X, however, so the poor Windows result probably won't matter to most Safari users.'"

      I have to agree. I'm on a Macbook Pro now and using Snow Leopard with it's 64-bit Safari. Everyone is saying how fast and quick Safari is...along with Chrome, but the simple fact is both of these browsers don't have Adblock so they're actually SLOWER than Firefox with Adblock because they all have to load in those ads.

      Maybe Safari and Chrome are fast on a test....but in real world situations without adblock, they're slow.

            Very simple experiment - obtain a temperature monitor that can show you CPU and GPU temperatures. (This usually needs discrete graphics, although some integrated graphics systems hide the northbridge temperature as the "PCI" temperature.) Monitor CPU load, as well.

            Start a flash video in IE. Note what happens to all temperatures - CPU load will be low, CPU temps won't change much, GPU temps will rise.

            Now, start a flash video in any other browser (that isn't IE-based.) CPU load will be (comparatively) high, and CPU temps will rise. GPU temps will stay steady, or at most climb a couple degrees just because of being heated by the CPU.

      But the thing is, IE processing pages with ads and flash was *more* efficient and less demanding on the CPU than Firefox processing pages with no ads at all.

      That comes to me as quite a shock, given that Flash is, in fact, a pig.

        Kindof. It may just mean that the flash plugin for IE is less battery intensive than the flash plugin for FF.

        We'd have to no-flash, flash-only, and a mix to figure it out. The tests here didn't.

        This can't turn into a comparison of Microsoft vs Mozilla... it's probably more like a comparison of Adobe programmers on different teams.

        No, really. It's a meaningless number.

        There's no control in this experiment (and, no, I don't mean "control group.") The fact that they were flogging away at public, and probably dynamic (read: inconsistent) websites totally invalidates the entire comparison.

        If Anand wanted to take it seriously, they should have eliminated more variables. If they'd set up a dedicated, light-weight web server running in a controlled minimalist environment (bare Slackware+Apache, perhaps?) somewhere on a dedicated LAN, that would have been be a good start. They might even have used a RAM disk to ensure consistent access times to the data being served.

        Hell: They should have even measured the battery voltage both before and after the tests, to eliminate (or at least quantify) any incongruity in the charging circuit's behavior. And they should've made sure to rotate their testing, so as to average it out as the battery ages (which it quite measurably will in these relatively-abusive full-charge - full-discharge tests).

        But they didn't do these things. And it might seem like I'm splitting hairs here, but the results are close enough that hairs must be split.

        Meanwhile, I think battery life while browsing is an interesting and very practical metric which is often overlooked these days. I applaud them for attempting and documenting such a feat, which I'm sure was relatively time-consuming, and I admonish them for doing a piss-poor job of it.

        (And, no: I don't care which browser "wins." I have most of the tested browsers installed on my own laptop, and for me, it would be instructive to know which one will conserve battery life best in times when I know I'll be without power for a long period of time.)

            I'm no statistician, either, but your proposal sounds like it would be more difficult (define "random" in this context, including time of day), more time-consuming, and less accurate.

        No, seriously, who cares?

        If you get 2 hours of battery time, this gains you about 2 minutes and half.

        For 5 hours of battery time you get 6 minutes extra.

        If you really want to extend battery time, turning down the screen brightness by a notch will probably have more effect.

    *Why* IE 8 gets better battery life than Safari? Is it simply because IE 8 has better, more efficient code? Is it because Safari is spending more processor resources getting me my pages quickly? (in which case perhaps Safari still gives the highest battery measured by numbers of pages visited) Is it because of OS integration (all the tests were run on Windows Vista or XP) in which case isn't IE (a) cheating (b) introducing other tradeoffs (security, etc.)? A virus might ultimately cost me more battery life, so even if my battery life is the solitary end in which I place concern, these other factors are still relevant. It is an interesting report, but given that the results are very close, I think it's hard to draw any substantial conclusions from it (except that viewing ads costs battery life).

    What would be somehow an interesting test is to measure the number of cycles/instructions a browser needs to:
